MQ2 Sensor Module

MQ-2 Modul is a device that is used for sensing and measuring the concentration of gases in the air. It can detect such gases as: LPG, propane, methane, hydrogen, alcohol, smoke and carbon monoxide.
It can measure a gas concentration from 100 to 10000ppm and is ideal for detecting a gas leak, as a gas alarm or for other robotics and micro-controller projects.
The MQ series sensors use a small heating element with an electronic-chemical sensor. They are sensitive to various gases and are suitable for indoor use.
The sensor has a high sensitivity and fast response time, but needs a few minutes to give accurate readings because the sensor needs to heat up first.
The measured values of the sensor are output as analogue values, which can be easily evaluated with a micro-controller.
This sensor is ready for connection to a micro-controller, such as an Arduino board. For use with a Raspberry Pi an additional AD converter is required.
The module has a potentiometer for setting the threshold value. At the digital pin, the sensor outputs only a 0 or 1, depending on whether the set threshold value is exceeded.
